Whether you live in the snow belt or the sunny south, the winter season often means a change in the weather. In many places, the sun isn't as strong and cooler temperatures bring relief from the summer's heat. Yet even though it may be chillier outside, your body's need for hydration is the same as it was in the summer—and a lack of proper hydration can be bad news for your oral hygiene.

Everyone knows we need to drink plenty of water every day to stay healthy. It's important for good oral hygiene because water is the major component of saliva, which fights bacteria and helps neutralize the acids that cause tooth decay. Water also keeps the soft tissues of the mouth moist and healthy, and helps fight bad breath. In many communities tap water is fluoridated, which offers proven protection against cavities.

But in the middle of winter, fewer people carry around bottles of cold water for refreshment—and that's a shame, because we need it just as much! While indoor (and outdoor) air is often drier in winter, your body continues to lose water in the same ways. And if you keep up a healthy exercise routine (like jogging, snow sports or backyard fun and games), you still need plenty of hydration. An ice-cold glass of water may not be as appealing in January as in July…but it's just as important.

Of course, the water you drink doesn't have to be freezing cold to do its job. Hot tea (especially herbal tea) can be a healthy option for wintertime hydration. So is plain water without ice. Fruits and vegetables also contain lots of water, plus vitamins, fiber, and many more substances that are good for your body.

But there are some drinks you should avoid—or at least take in moderation. Regularly drinking coffee and tea can stain your teeth, and excessive caffeine may have negative health effects. Consuming alcoholic beverages can cause dry mouth, and may increase the risk of oral cancers. And, of course, drinks that contain sugar (including soda, some juices, and many coffee and hot chocolate beverages) are linked not only to tooth decay, but to other health problems as well.
